SPECIFICATION forming part of Letters Patent No. 284,834, dated September 11, 1883,

Application filed August 2t, 1891. (No model.) Patented in France-March 25, 1880, No. 135,773; in Germany July4, IBFO, I No. 16,056, and in England July 5, 1880, No. 2,743.

To all whom it may concern/. 7 Be it known that 1, PAUL E IE GAUOHOT,

of Paris, in the Republic of France, have invented certain Improvements in Machines for 5 Grinding Drinking-Glasses, Goblets, and other Articles, of which the following specification is a full description. 7

The invention relates more particularly to machines for automatically grinding on drink- IO ing-glasses, goblets, and other articles a series of facets without labor on the part of the at tendants or operatives beyond the placing of the articles in position and their removal, and the general superintendence of the machine.

It has for-its obj cct to secure the grinding of the several facets with regularity and uniform ity, and to insure the efficient operation of the several parts ofthe machine. I

Heretofore in automatic machines for grinding glasses the facets havecom'monly been ground so as tobear the same position relative to the axis of the article; but molded glasses, in cooling, do not retain the regularity in form and equality of thickness given them in the molds, and the facets, although regular with respect to the axis, are irregular with respect to its surface, varying in depth or'width. To overcome this difficulty it has been proposed to have the grinder make a certain numher of revolutions to each facet; but in this system the head of the facet is ground more or less deeply, as the material to be ground off lies toward the base of the glass or toward the base of the facets, and an inequality in the 3 5 length of the facets is made. Moreover, more material must be ground off in making the first facets than in subsequent ones, and in the intermediate ones than in the last one, and a new cause of inequality thus arises, for

40 the grinder will remove the material faster at the end than at the beginning of the operation. In the present invention uniformity in the facets is secured by means of a finger or contact device which is acted upon by the glass near the heads of the facets and stops the grinding as soon as the desired depth has been reached. This finger also controls the glassholder, so that it is turned into position for cutting a new facet.

The invention'consists, mainly, in the system .50 of controlling the grinding of the facets; butit also comprises particular constructions and combinations ,of various parts, applicable in whole or in part to machines in which the control is effected 011 other systems.

The accompanying drawings, which form a part of this specification, illustrate a machine constructed in accordance with the invention, and adapted to grind drinking-glasses, tumblers, or goblets.

Figure 1 is a side elevation, partly in sec= tion; Fig. 2, an end elevation; Fig. 8, a par tial longitudinal section; Fig. 4, a general plan, partly in section; Fig 5, a transverse section; Fig. 6, a partial plan, showinginterior construction; Fig. 7, a partial side view in section and elevation, looking in the oppo= site direction from Fig. 1. Fig. 8 is a- View similar to Fig. 7, only the section is taken in a different plane; Fig. 9, apartial view in vertical transverse section and in elevation, looking in the opposite direction to Fig. 5; and Fig. 10, an enlarged detail view.

The various parts of the machine are supported on a frame, 1. The grinder 400, which may be an emery-wheel, a cast-iron disk to be used with sand, as customary, or may be made of any suitable material, is supported (see Fig. 4) on a shaft, 29, which is held in place by boxes 3 upon a standard,,2. The grinder at the center is clamped between annular plates fastened to the sleeve 7, which passes through the eye of the grinder, and is or may be made in one piece with one of said plates. The sleeve is held onto the shaft 29 by the screw 8 5 28, and turns therewith. On the shaft are placed a drivingpulley, 5, a loose pulley, 6, and a fast-grooved pulley, 4. v

The holder for the glass or other article (see Fig. 5) consists of two centers, 40 73, which fit, the latter in the interior (when the article is of proper shape) and the former against the bottom, and which are both provided with plates or coverings of flexible material where they bear against the glass. The 9 5 center 40 is held loosely in the end of an ad-' justable slide, 39. The center 73 has a tapering base which fits within a conical hole in the piece 37, and is held from turning independwheel; 66.

The carrier 27, which supports the glassholder, is pivoted by bolts 105 to abox, 26, which is itself swiveled to a slide, 25, that slides in ways of the frame 1. The slide 25 is adjusted toward and away from the grinder by means of a screw, 36, (see Fig. 3,) and a spring, 93. The screw 36 is secured to a piece, 17, fastened to the frame 1. It passes through a hole in the end wall of slide 25, and at its outer end is engaged by a nut, 19, which can be turned by a hand-wheel, 22. The spring 93 surrounds the screw 36, and bears at one end against the fixed piece 17 and at its other against the end wall of the slide.

The bottom of box 26 fits around the cylindrical piece 14, Figs. 3 and 5, bolted to the slide 25, and is adjustable around a vertical axis (see Fig. 6) by means of a fixed segment, 61, and a worm, 48, carried by the box and operated by a hand-wheel, 54. The carrier is not supported wholly by the bolts 105 but a lever, 81, which projects from the side of the box and rests upon the top of a coiled spring, 92, extends under the carriers center of gravity and sustains the greater part of the weight by contact with .the projections 63 from the bottom of the carrier. By these means the carrier is enabled to be rocked with little power to bring the article in the holder in contact with the grinder.

The carrier is rocked forward by means of a weight, 75, attached to an arm of a rockshaft, 18, supported in bearings in the swiveled box 26, through a link, 41, Figs. 1, 2, and 4, jointed to a short arm, 18*, of the rock-shaft, and connected with the upper part of the carrier. The connection with the latter is adj ustable, and is made by a rod, 52, which can be raised and lowered in cars on the carrier by a nut, 82, engaging a screw-thread on the rod. After the facet has been ground to the required depth, the article strikes a finger, which brings into operation a train of mechanism for withdrawing the holder. This is also constructed to turn the article, so as to present it in position for grinding a new facet. This controlling-finger or contact device 70, Figs. 4 and 10,

is attached to a movable cap, 62, Fig. 3, and the latter to the hollow standard 24, which is attached to or made in one piece with the slide 25, so that when the latter is adjusted by the hand-wheel 22 it is moved with it and can be set nearer to or farther from the periphery of the grinder, and thus allow facets of varying depth to be cut. The controlling-finger is also adj ustably connected with the cap 62 by means of a slot, 403, and set-screw 402, so that it can be set as close as may be desired to the side of the grinder. The cap 62 has a supportingpiece, 404, bolted to the top thereof, on its under side. A pivot or journal pin, 401, connects the said piece with the standard 24, and allows the cap 62 to be rocked thereon. A spring,

91, (more than one can be used, if desired,) upholds the rear (right hand, Fig. 10) end of the cap and its supporting-piece, except when pressure against the finger 70 tilts the cap 62 and compresses the said spring. A catch, 33, attached to the supporting-piece 404, normally engagesa similar catch on the end of the upright arm of lever 20, but releases it when the cap is tilted by pressure against the finger 7 0, the said catch being then forced downward out of engagement. The said lever is ful- 8o crumed in the body of the slide 25. A counterpoise, 84, moves lever 20when released, and the horizontal arm of the lever starts the train of mechanism before referred to, which will now be described.

A shaft, 35, turns in bearings in slide 25, its front (right hand, Fig. 5) end being journaled in the piece 14. At the rear end is a clutch wheel, 11, supported on the shaft, so as to turn with it, but capable of a limited move- 0 ment lengthwise of the shaft. In the boss of the clutch-wheel, and surrounding the'shaft, is a spring, 94, which tends to press the clutchwheel outward into contact with a grooved pulley, 10, loose on the shaft, and receiving-its 5 motion from the grooved pulley, Figs. 1, 2, and 4, on the main shaft. An idler, 78, is car- 'ried by an arm, 80, which is adjustably connected with arm 23 of the frame 1 by a screw, 110. The belt extends over the top of idler 78, under the pulley 10, and around the pulley 4, being crossed between the pulley 4 and the other p'ulleys, as shown by the broken line, Fig. 1.

A clutch-lever, 21, Fig. 5, carried by the slide 25, serves to withdraw the clutch-wheel 11 from contact with the pulley 10 and force it against a stationary brake, 109. The upright arm of thelever 21 acts against a shoulder on the boss of the clutch-wheel, and the IIO horizontal arm is provided with a weight, 88, heavy enough to draw back the clutch-wheel 11 against the force of its spring. This is the position of the clutch-whee1 during the cutting or grinding operation. As soon as the lever 1 I 5 20 is released by the action of the controllingfinger 70, Fig. 3, upon the catch 38, it is operated by the weight .84, and its inner arm lifts the horizontal arm of clutch lever 21, whereupon the spring 94, being released, forces I 20 the clutch-wheel 11 into contact with the pulley 10 and looks it to the shaft 35, so that this immediately begins to revolve. Motionis communicated through the bevel-gears 16 15 to an upright shaft, 405, having at the top a spur- 12 5 pinion, 55, which engages with a spur-gear, 60, Fig. 3, turning upon a Vertical shaft carried by box 26, and connected with the cams 64. The upper of these cams acts upon an arm, 58, of the rock-shaft 18, and tiltsback the I 30 carrier 27 and the glass-holder through the link: 41., Figs. 1 and 2, and connections, so that the article being ground is withdrawn from contact with the grinder. In Fig. 3 the end of the arm is shown in a'raised position above the recess, into which it descends as the carrier and glass-holder are swung forward by the weight 75.

The lower cam 64 acts upon the arm 57 of the rock-shaft 108, and by connectionwith said shaft (best shown in Fig. 7) moves the piece 37 and center 73 of the glass-holder one step, so as to present a new surface for grinding. It also, through the piston 34, Figs. 3 and 5, which is jointed to the outer end of the arm 57, resets the lever 20 and shifts the clutchwheel 11, so as to stop the motion ofthe shaft 35 and cams 64.

On the boss of the piece 37 which supports the center 73, Figs. and 7, is secured a cylindrical ratchet, 200, which is prevented from turning 011 the boss by a key or similar means, and is held from lengthwise movement by a shoulder on the piece 37 at one end and a shoulder on the slide 38 at the other. This ratchet, and with it piece 37 and center 73 and the article held 011 the center, each time the carrier is tilted back, is revolved one ratchettooth by means of an operating-pawl, 50, and is held in place during the grinding operation by a stop-pawl, 45, supported on the stud 44, and held in engagement with the ratchet by a spring, 103. The pawl is carried by a ring, 46, which is vibrated by an arm, 49, of the shaft 108 through a link, 47. The ring has an arm in which are a series of holes, in which the upper end of the link may be connected at different points to lengthen or shorton the movement of the ring 46 and pawl 50.

The ratchet 200 can be readily removed and replaced with one of a greater or less number of teeth by withdrawing the piece 37 from the slide 38 and taking the ratchet off the boss, placing the new ratchet in position,.and ,returning the piece 37.

It is obvious that the operatingpawl may have the same amount of motion for a limited number of ratchets with different numbers of teeth, so that it is necessary to alter the con nection of the link 47 with the ring 46 only when a great variation is to be made. The parts are so arranged that the operatingpawl always brings each ratchet-tooth to the same position, irrespective of the amount of motion.

The lever 21, Figs. 3 and 5, when lifted by the lever 20, is engaged by a catch, 42, having aspring, 106. The piston has at its lower end a cone for releasing this catch. When the arm 57 is pressed down by the lower cam 64, it carries with it the piston 34. The latter passes by the end of the lever 21, which is located on one side, (left, Fig. 5,) but strikes the horizontal arm of lever 20 and forces it down until the upright arm is engaged by the piston.

In operation, therefore, as soon as a facet of the desired depth has been cut on the article the latter strikes the controlling-finger 70, the catch 33 is moved and the lever 20 released, the weight 84 tilts the lever 20 and lifts the horizontal arm of lever 21, the spring 94 forces the clutch-wheel 11. into engagement with the pulley 10, the shaft 25 and cams 64 rotate, the carrier 27 is tilted back on its pivots 105, so

that the grinding is at once stopped, the

ratchet 200 is moved forward one step by the pawl 50, the lever 20 is reset, the horizontal arm of lever'2l is allowed to fall, the clutchwheel is drawn out of engagement with the pulley and into contact with the brake 109, and the shaft 25 and cams 64 stop, the carrier 27 and glass-holder 40 73 are tilted forward by the weight 75, and the grinding of a new facet begins. v

-It will be seen, therefore, that when a facet is ground to the required depth, which is the same for each facet, the articleis automatically withdrawn and shifted to present a new surface until all the facets havebeen ground.

In order that the machine may stop itself when the facets have all been cut or ground, the following devices, Figs. 3, 7, and 8, are employed: A stop-lever, 43, pivoted to the carrier 27, projects at its upper end into contact with the piece 37, which has in its periphery a deep recess, 99, into which the end of said lever drops when the said recess comes under it. It is provided that the recess.99 shall come under the end of stop -lever 43 when the glass-holder has made a complete revolution, or, in other words, when the facet first cut is brought into position for grinding again. The tail of the stop-lever rests'on a pin, 101, attached to the bent lever 102, itself supported on a stud projecting from the box 26. The long arm of lever 102 is provided with aweight, 51. Its shorter arm can be moved into and out of the path of the toe 74 of rock-shaft 18, so as to catch said toe or allow it to pass, according to its position. When, therefore, the upper end of the stop-lever 43 drops into its recess, which takes place while the glassholder and its carrier are tilted back by the upper cam 64,and while the weight 75 is elevated, the lever 102 drops back under the action of weight 51, and the short arm thereof moves under the toe 74, so that when the arm with lever 102 and the carrier 27 is not advanced. The shaft 35 and cams 64 are stopped as before explained.

After an article has been ground, a new article is placed between the centers 73 and 40, and the operator lifts weight 51, thus moving the short arm of lever 102 from under the toe 74 and allowing the weight 75 to press the article against the grinder. The machine then operates automatically until a series of facets have been ground. A pipe provided with a stopcock delivers water through the device onto the grinder and the article being ground, thus carrying off the heat and washing away the ground-off material. The pipe is supported on the upright 24. An arm, 107, extends upward in front of the grinder, and serves as a rest for a tool when it is desired to trim down the surface of the grinder.

A belt-shifter, 67, operated by the handwheel and nut 13, is employed to shift the belt from the driving-pulley 5 to the loose pulley 6 when it is desired .to stop the machine. The adjustment of the slide 25 by the hand-wheel 22 enables the facets to be cut to any desired depth, and also permits the wear on the grinder to be compensated for.

The turning of the box upon the fixed piece 14, as on a swivel, determines the conicity or slope of the facets to be ground. A regular adjustment of the box does not interfere with the operation of the cams 645, since the pinion 55 and bevel-gears 15 turn on the same axis as the box.

' To prevent the vibration of articles with feet-such as goblets-and to prevent them from breaking in cutting or grinding, the shank or leg of the article is or may be enveloped in a mass, say, of lead, which is held in place by suitable means. In order that the adjustment of the controlling-finger may be effected with accuracy, the boss of the hand wheel for operating the slide maybe graduated.

It is obvious that various modificationsmay be made without departing from the spirit of the invention; also, that portions of the invention may be used without the others.

The term glass-holder, used in this speci fication, is not to be understood as a holder for drinking-glasses, goblets, or tumblers, but

'as a holder generally for the article to be cut or ground, whatever be its shape or material. So, also, the term grinder or cutter includes any device by which the surface, is worn away or otherwise removed in a manner similar to a grinding or cutting operation.

Having now fully described my said invention and the manner of carrying the same into effect, what I claim is 1. In combination with a grinder or cutter and a holder for the article to be ground or cut, a controlling-finger and connected mechanism for stopping the grinding or cutting operation by contact of the controlling-finger with the surface of said article, substantially as described.
